SWITCH-STAND.

SPECIFICATION forming part of Letters Patent No. 294,100, dated February26, 1884.. 1 Application filed February 12, 1883. (No model.)

To all whom it may concern:

Be it known that I, Freeman 0. WEIR, of Cincinnati, inthe county ofHamilton and State of Ohio, have invented certain new and 5 usefulImprovements in Switch-Stands; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, and

I to the figures and letters of reference marked thereon.

My invention consists in certain novel improvements in railroad switchstands or ground-switch throws, which I will first de- I scribe, andthen point out particularly in the claim at the end of thisspecification."

In the accompanying drawings, Figure 1 represents a perspective view ofmy invention; Fig. 2, an end elevation of the same with the slidingplate removed 5 Fig. 3, a sectional view taken on the linear w of Fig.2; Fig. 4, a plan View with a portion of the casing removed.

Similar letters of reference in the several 2 5 figures denote the sameparts.

Arepresents the body of the switch-stand, consisting, preferably, of asingle piece of metal, cast or otherwise formed with the horizontal andvertical bearings for the shafts D and G, respectively, a chamber, B,for inclosing the gears E and F upon said shafts D and E, and withsuitable perforatedlugs, a b, by which it may be spiked downfirmly tothe sills or cross-ties.

3 5 0 represents the actuating lever of the switch, rigidly attached tothe shaft D, and carrying upon it the crank-pin I, to which is adaptedto be connected the pitman or connecting-rod leading to. the ordinaryti'ebar of 0 the switch-rails.

The lever C may be provided with a slot, K,

ing-staple, as ordinarily; or it may be provided with an adjustableweight, 0, as showndn Figs. 2, 3, and 4.

The bevel-gear E on the horizontal shaftD meshes into the correspondingsegmental gear, F, on the vertical shaft G, and said shaft G carries atarget, H, or a lantern, to give the appropriate signal to indicate inwhich position the switch is shifted.

The sliding plate J covers the opening leading into the chamber B, andeffectually incloses the gears and protects them from access of dirt,snow, and rain.

From this construction it will be observed that all the journals andbearings of the parts are arranged within the main casting and 00- copya fixed relation to each other, while the gearing is completely housedfrom the weath- 6o er, though accessible, when'desirable for oiling andother purposes, through the opening covered by the removable slide.

Having thus described my invention, I claim as new I The combination ofthe chambered cast-ing having the horizontal and vertical bearings ofthe shaft D, target-shaft G, gears E and F, inclosed within the casting,and the weighted lever 0, rigidly attached to shaft D, and carrying thecrank-pin I, to which the pitman or conv necting-rod is adapted to beconnected, the whole arranged and operating substantially as described.

In testimony whereof Ihave hereunto set my hand in the presence of twosubscribing witnesses.

FREDRIG o. WEIR.
